I don't know any well-known writers or musicians with one or both of these placements off the top of my head, but you can conduct specific searches for these placements through the
Astrotheme database, which contains tens of thousands of celebrity natal charts.
You may need to become a member to do one of these advanced searches, but membership is free...
EDIT: Actually, I don't think you even need to become a member to locate these charts; I can't find the specific search feature that I was referring to, but you can search manually by clicking on the different categories in
Celebrity Index.
It took me a few minutes, but I found the
Advanced Search--and you don't even need to register to use it!
You will find here the list of the famous people having the following characteristics in their map of the heavens:
Sun in House XII
